Five states now do, and seven others may soon follow—including Texas, where a shooting just shook up a community college.

On Tuesday, a dispute between two people at Lone Star College in Houston ended in a gun fight. Three people were wounded (including suspects in the shooting), and a fourth person was reportedly hospitalized with an unspecified "medical emergency" in connection with the incident. It was the sixth shooting on or near a US college campus this month.

Texas generally has lax gun laws, but prohibits carrying a concealed weapon on a college campus. The GOP-controlled Texas Legislature may soon change that, however. Last week, state Sen. Brian Birdwell, a Republican, introduced new "campus carry" legislation that would allow firearms to be carried at public colleges with a valid permit. Texas would join five states* that, to varying degrees, now allow weapons to be carried on campuses. And lawmakers in at least seven other states are aiming to follow suit.

Does your state allow concealed guns on college campuses? Hover over an individual state for further details. (Also see lists below the map.)

States in which lawmakers have recently introduced legislation to allow guns on campuses: Arkansas, Georgia, Indiana, Kansas, Michigan, Missouri, and Wyoming.

Correction: California was included in this category in the initial version of the story; the state bans concealed guns on college campuses but makes exceptions for individuals with valid licenses who are granted specific permission by school authorities.
